Answer:
The scientist can use only the angle x and the distance y to calculate the distance between the Earth and the Sun using the cosine function.Step-by-step explanation:
The cosine of an angle is equal to the ratio of the length of the adjacent side and the length of the hypotenuse. In equation form:
cos x = BC / y
Solving for BC
BC = y cos x
BC is the distance between the Earth and the sun

Step-by-step explanation:
You want to save all the money you earn to buy a guitar that costs $400. You earn $9 per hour and
plan to work 15 hours each week for the next 3 weeks. Will you earn enough money in that time to buy
the guitar? Explain your answer.
15 hours × 3 weeks × $9 per hour
15 × 3 × 9 =
45 × 9 = 405$
The answer is YES
Answer:
about 30 then you will still fall short of that mark

Answer:A=183cm^
Step-by-step explanation:
The area of square is :
Let s be side
A= s^2
144= s^2
Square both side
Therefore
s=sqrt(144)
s=12 cm
The perimeter of the square is : 4× s= 4×12= 48cm
So the perimeter of the square is equal to the circumference of the circle.
The equation will be:
4×s=2×pi×r
4×12=2× (22/7)×r
r=48/6.29
r=7.63
Area of a circle is:
A=pi× r^2
A= (22/7) × (7.63)^2
A=182.9674cm^2
A=183cm^
